What GPU Do You Need for Hermes-4-70B?, tok/s by GPU
Efficiency: tok/s per 100W drawn
Power is the average pulled during the run, sampled at 1Hz. The fastest card is often not the one here, and for anything left running this is the number that shows up on the bill.
Value: tok/s per $1,000 of MSRP
Launch price, not street price, so it ages. A speed leaderboard always crowns the most expensive card; this is the counterweight.

Cheapest hourly rate we track on RunPod and Vast.ai, divided by the measured speed. Startup time and storage are extra.
Speed tiers for Hermes-4-70B. 30+ tok/s: 5 (B300, B200, H200); 10-30 tok/s: 2 (A100 80GB SXM4, L40S). 30 tok/s is roughly where replies outpace reading.
Reading your prompt. Before Hermes-4-70B writes anything it reads the input: 1766.0 tok/s on the RTX PRO 6000 Blackwell Workstation Edition (2.3s for a 4,000-token prompt), 541.7 on the A100 80GB SXM4 (7.4s). Long documents and big code files feel this number more than the generation speed.
VRAM for Hermes-4-70B. Measured peak 40.5GB, so 48GB is the smallest common card size; smallest card it ran on: L40S (48GB). With long context: Q4_K_M 54GB (tested), Q6_K 74GB, Q8_0 96GB.
Power on Hermes-4-70B. Most efficient: H100 80GB HBM3, 370W, 2.49 kWh per 1M generated tokens. Hungriest: B200, 582W, 3.64 kWh. At $0.15/kWh: $0.37 per 1M generated tokens.
Our verdict
Fastest on Hermes-4-70B: NVIDIA B300, 48.1 tok/s. Cheapest to rent per job: NVIDIA RTX PRO 6000 Blackwell Workstation Edition, $9.19 per 1M generated tokens.

How we test
llama.cpp llama-bench at Q4_K_M, 512-token prompt and 128 generated tokens, three runs after a warmup, full GPU offload, with power and VRAM sampled throughout. Token generation is memory-bandwidth-bound, so the ranking tracks bandwidth closely, which makes it a fair guide to cards we haven't run yet.
